Help with thermal camera design
« on: April 25, 2017, 01:41:28 pm »
I'm designing a thermal camera using a sensor from ULIS which outputs an analog signal output which needs to be processed inorder to obtain the image. Please check the attachment for the waveform output.

I'm thinking of using a CCD sensor Analog Front End like Are there any problem in using a CCD sensor AFE for this a non-CCD sensor, taking into consideration that the output doesn't have a waveform expected from a CCD sensor. Also the AFE has an input of 2V and the sensor output swings between 0.5V and 2.9V. Other than using a simple resistor divider, is there any other better methods for scaling down the signal considering aspects like signal integrity etc.. What about a difference amplifier as shown here to achieve a gain less than unity?

I just saw this post today. No, CCD sensor AFEs are not the right choice for your design.
